Abstract

Plasma iron levels are decreased in Alzheimer's disease (AD) and associated with an idiopathic anemia. We examined iron-binding plasma proteins from AD patients and healthy controls from the Australian Imaging, Biomarkers and Lifestyle (AIBL) Flagship Study of Ageing using size exclusion chromatography-inductively coupled plasma-mass spectrometry. Peak area corresponding to transferrin (Tf) saturation was directly compared to routine pathological testing. We found a significant decrease in transferrin-associated iron in AD that was missed by routine pathological tests of transferrin saturation, and that was able to discriminate between AD and controls. The AD cases showed no significant diff..
